720s without a FPR

[4g63RAW]

I want to put on my desno 720 cc injectors but im not sure how my car will run. I have an AFC to lean them out but I dont know if it is better to wait and get a fpr.

just wondering.. what was the answer...?

A FPR has nothing to do with the injectors you run. Wether or not you need a FPR is based soley on the choice of fuel pump you run.

I beg to differ.....Many times people are able to use smaller injectors by bumping up the base fuel pressure with their afpr....

But that has nothing to do with his question. His question was would his car run ok with 720s and an AFC without an AFPR. The only thing the AFPR would do is regulate the fuel pressure coming from the fuel pump. I understand you can raise your fuel pressure with an AFPR which would essentially be like running a slightly larger injector but it has nothing to do with his question.

Correct but you just said a fpr has nothing to do with your injectors, and that as a blank statement is incorrect....

Sorry I was speaking in context with the original post. I will be more specific in the future
